Description

Technical Field

[0001] This utility model belongs to the field of automotive repair technology, specifically relating to a vehicle tilting device for automotive repair. Background Technology

[0002] During long-term use, cars inevitably require maintenance and repair. During maintenance, it's usually necessary to tilt the car along its length. Firstly, this allows for a more thorough draining of the old engine oil. While the drain plug is at the lowest point of the oil pan during an oil change, the oil pan isn't perfectly horizontal. Tilting the vehicle creates a slope, allowing the oil to flow more thoroughly towards and collect near the drain plug hole under gravity, thus removing as much old oil as possible. The less old oil remains, the less the performance of the new oil is affected. Secondly, tilting the vehicle makes it easier to access specific parts of the chassis. For example, tilting the car allows the suspension components to be in different extension or compression states, facilitating the inspection of bushing wear, clearances, and sources of abnormal noises. Changing the vehicle's tilt angle also provides better maneuvering space when disassembling and installing certain parts of the exhaust pipe.

[0003] In existing technologies, a lift (or jack) is typically used to raise the front or rear of the vehicle, thereby tilting the vehicle. To ensure stability, ropes are often threaded through the vents on both sides of the wheel hub and tightened to limit wheel movement and prevent slippage. However, the process of threading and tightening ropes is cumbersome, reducing overall maintenance efficiency. Furthermore, because ropes have a certain degree of elasticity, the vehicle will sway under external forces during maintenance, affecting the precision of the repair operation. Long-term swaying can also cause wear at the contact point between the rope and the wheel hub. If the rope breaks, it will pose a threat to surrounding personnel and equipment. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a vehicle tilting device for automobile repair, so as to solve the technical problem that the existing technology uses ropes to pass through the air vents on both sides of the wheel hub and tighten them, resulting in poor vehicle fixation.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A vehicle tilting device for automobile repair includes a tilting support and a climbing frame located on one side of the tilting support. The tilting support includes a base plate and a top plate located directly above the base plate. A support column and a hydraulic cylinder are provided between the base plate and the top plate. The support column and the top plate are rotatably connected by a hinge assembly. Extension plates are provided on both sides of the top plate. A vertical mounting plate is provided on the top of the extension plates. The mounting plate and the extension plates are slidably connected by a sliding assembly. A locking unit is slidably connected to the inner side of the mounting plate. The locking unit includes a locking disc. A radially extending limiting groove is opened on the inner plate surface of the locking disc. The limiting groove is evenly spaced along the circumferential direction. An "L"-shaped limiting frame is slidably connected in the limiting groove. The limiting frame includes a sliding section and a locking section that are perpendicular to each other. The locking section extends out of the outer side of the locking disc in a direction parallel to the axis of the locking disc. A push-pull rod is rotatably connected to the outer side of the limiting frame. The push-pull rod passes radially through the side of the locking disc and is threadedly connected to the locking disc.

[0007] Furthermore, the hinge assembly includes a pair of support blocks fixedly connected to the top surface of the support column, with a gap between the support blocks. The hinge assembly also includes a connecting block fixedly connected to the lower surface of the top plate. The free end of the connecting block is inserted into the gap between the support blocks. The rotating shaft passes through the support blocks and the connecting block on both sides in a horizontal direction. The top plate rotates around the rotating shaft under the action of external force.

[0008] Furthermore, the free end of the hydraulic cylinder output shaft is formed with an arc-shaped end, which allows the hydraulic cylinder to make line contact with the top plate, and the hydraulic cylinder output shaft can slide relative to the top plate during the lifting process;

[0009] Furthermore, a groove is formed on the upper surface of the extension plate. The groove extends along the width direction of the extension plate and the length of the groove is the same as the width of the extension plate. A slider is provided at the bottom of the mounting plate. The slider is slidably connected to the groove. A limiting plate is provided at the outer opening of the groove. A limiting groove is formed inside the slider. A limiting rod is threaded on the upper part of the limiting plate. The inner end of the limiting rod forms a limiting end that matches the limiting groove. The limiting rod extends into the slider and the limiting end enters the limiting groove. The limiting rod and the slider form a rotatable connection.

[0010] Furthermore, the mounting plate has elongated sliding holes, the back of the locking disc contacts the inner surface of the mounting plate, and locking plates are spaced apart on the back of the locking disc. The locking disc and the locking plates are connected by a sliding post, which slides in connection with the sliding hole. The locking plate has locking screw holes, and the locking screw passes through the locking screw holes and presses against the mounting plate, thereby fixing the entire locking unit to the mounting plate.

[0011] Furthermore, the sliding section is located in the limiting groove and is slidably connected to the limiting groove. Sliding limiting grooves are provided on both sides of the limiting groove, and sliding limiting blocks are provided on both sides of the sliding section. The two match each other to prevent the limiting frame from detaching from the limiting groove during the sliding process.

[0012] Furthermore, a hemispherical fixed shell is fixedly connected to the outer surface of the limiting frame, and a rotating hemisphere is rotatably connected inside the fixed shell. A coaxial connecting rod is welded to the inner end of the push-pull rod, and the connecting rod rotates through the connecting through hole at the top of the fixed shell and is fixedly connected to the rotating hemisphere.

[0013] The beneficial effects of this utility model are as follows:

[0014] Compared with existing technologies, the locking unit offers several advantages. First, it simplifies operation; the wheel can be limited simply by rotating the push-pull rod. Second, the locking section of the limiting bracket makes multi-point contact with the wheel hub, effectively limiting the wheel and preventing it from rotating. This prevents the vehicle from slipping or swaying under external forces. Furthermore, adjusting the spacing between the mounting plates accommodates different track widths, and adjusting the distance between the locking units on the same side accommodates different wheelbases, thus expanding the applicability of the tilt support to some extent.

Detailed Implementation

[0028] Example 1, specifically as follows Figures 1-10 As shown.

[0029] A vehicle tilting device for automobile repair includes a tilting support 1 and a climbing frame 2 located on one side of the tilting support 1. The sloping climbing frame 2 is located on one side of the tilting support 1 in the width direction. The vehicle to be repaired is moved to the top of the tilting support 1 via the climbing frame 2.

[0030] The inclined support 1 includes a base plate 101 and a top plate 102 located directly above the base plate 101. A support column 103 and a hydraulic cylinder 107 are provided between the base plate 101 and the top plate 102 to provide support for the top plate 102. The support column 103 is distributed on one side near the climbing frame 2, and the hydraulic cylinder 107 is distributed on the other side near the climbing frame 2. Both the support column 103 and the hydraulic cylinder 107 are located on both sides of the top plate 102 in the width direction.

[0031] The support column 103 and the roof plate 102 are rotatably connected by a hinge assembly. Specifically, the hinge assembly includes a pair of trapezoidal support blocks 104 welded to the top surface of the support column 103, with a gap between the support blocks 104. The hinge assembly also includes a connecting block 105 welded and fixed to the lower surface of the roof plate 102. The free end of the connecting block 105 is inserted into the gap between the support blocks 104. The rotating shaft 106 passes horizontally through the two support blocks 104 and the connecting block 105. By setting the hinge assembly, the roof plate 102 rotates around the rotating shaft 106 under the action of external force, thereby causing the vehicle to tilt. In addition, it is worth noting that the middle part of the roof plate 102 is open, forming an operating window. Maintenance personnel stand below the roof plate 102 and pass through the operating window to perform maintenance on the vehicle.

[0032] The output shaft of the hydraulic cylinder 107 abuts against the lower surface of the top plate 102, supporting the top plate 102. By changing the stroke of the hydraulic cylinder 107, the top plate 102 is driven to rotate around the rotating shaft 106. It is worth emphasizing that the free end of the output shaft of the hydraulic cylinder 107 has an arc-shaped end 1071, which allows line contact between the hydraulic cylinder 107 and the top plate 102, enabling relative sliding between the output shaft of the hydraulic cylinder 107 and the top plate 102 during the lifting and lowering process.

[0033] Limiting frames 108 are provided on both sides of the contact position between the arc-shaped end 1071 and the top plate 102. The output shaft of the hydraulic cylinder 107 is limited by the limiting frames 108 to prevent deviation.

[0034] The top plate 102 has extension plates 109 of equal length on both sides. The upper surface of the extension plates 109 overlaps with the upper surface of the top plate 102. A vertical mounting plate 110 is provided on the top of the extension plates 109. The mounting plate 110 is the same length as the extension plates 109. The mounting plate 110 and the extension plates 109 are slidably connected by a sliding assembly. Specifically, the upper surface of the extension plate 109 has a groove 111. The groove 111 extends along the width direction of the extension plate 109 and its length is the same as the width of the extension plate 109. A slider 112 is welded to the bottom of the mounting plate 110. The slider 112 is located in the groove 111 and the two are slidably connected. A limit plate 114 is welded to the outer opening of the groove 111. A limit groove 113 is provided in the slider 112. A limiting rod 115 is threadedly connected to the center of the limiting plate 114. The inner end of the limiting rod 115 forms a limiting end 1151 that matches the limiting groove 113. The limiting rod 115 extends into the slider 112, and the limiting end 1151 enters the limiting groove 113. The limiting rod 115 and the slider 112 are rotatably connected.

[0035] By rotating the limiting rod 115, the mounting plate 110 is driven to slide along the length of the slide groove 111, thereby adjusting the horizontal distance between the two mounting plates 110.

[0036] The mounting plate 110 has a locking unit slidably connected to its inner side. Specifically, a long sliding hole 1101 is provided in the middle of the mounting plate 110, and the extension direction of the sliding hole 1101 is consistent with the length direction of the mounting plate 110.

[0037] The locking unit includes a disc-shaped locking disc 116. The back of the locking disc 116 contacts the inner surface of the mounting plate 110. Circular locking plates 118 are spaced apart on the back of the locking disc 116. The locking disc 116 and the locking plates 118 are connected by a sliding post 117, which is slidably connected to a sliding hole 1101. A locking screw hole is provided on the locking plate 118, through which a locking screw 119 passes and presses against the mounting plate 110, thereby fixing the entire locking unit to the mounting plate 110.

[0038] A radially extending limiting groove 120 is formed on the inner plate surface of the locking disc 116 on the side away from the mounting plate 110. The limiting grooves 120 are evenly spaced along the circumference. The number of limiting grooves 120 can be adaptively adjusted according to the specific structure of different wheel hubs. In this embodiment, considering that most wheel hubs adopt a 5-spoke structure, the limiting grooves 120 are also set to 5. An "L"-shaped limiting frame 121 is slidably connected in the limiting groove 120. Specifically, the limiting frame 121 includes a sliding section 1211 and a locking section 1212 that are perpendicular to each other. The sliding section 1211 is located in the limiting groove 120 and is slidably connected to the limiting groove 120. The locking section 1212 extends out of the outer side of the locking disc 116 in a direction parallel to the axis of the locking disc 116. It is worth further explaining that sliding limit grooves are provided on both sides of the limiting groove 120, and sliding limit blocks are provided on both sides of the sliding section 1211. The two are matched to prevent the limiting frame 121 from separating from the limiting groove 120 during the sliding process.

[0039] A push-pull rod 122 is rotatably connected to the outer surface of the limiting frame 121. The push-pull rod 122 passes radially through the side of the locking plate 116 and is threadedly connected to the locking plate 116. A hemispherical fixed shell 123 is welded to the outer surface of the limiting frame 121. A rotating hemisphere 124 is rotatably connected inside the fixed shell 123. The rotating hemisphere 124 completely fills the internal space of the fixed shell 123. A coaxial connecting rod 125 is welded to the inner end of the push-pull rod 122. The connecting rod 125 rotates through the connecting through hole 1231 at the top of the fixed shell 123 and is fixedly connected to the rotating hemisphere 124.

[0040] In use, first, connect the climbing frame 2 to the inclined support 1 and drive the vehicle to be repaired onto the top plate 102; then remove the climbing frame 2 to prevent it from affecting the rotation of the top plate 102; then, push the mounting plates 110 on both sides to adjust the distance between them to match the wheel track, and slide the locking unit on the same side along the sliding hole 1101 to adjust the distance to match the wheel track; finally, insert the locking section 1212 of the limiting frame 121 into the wheel hub vent, rotate the push-pull rod 122, and the push-pull rod 122 moves radially outward, thereby driving the limiting frame 121 to move synchronously in the limiting groove 120, and the locking section 1212 expands outward to abut against the edge of the wheel hub vent, thereby limiting the wheel hub and wheel.

[0041] By incorporating a locking unit, operation is simplified; the wheel is limited simply by rotating the push-pull rod 122. Furthermore, the locking section 1212 of the limiting bracket 121 contacts the wheel hub at multiple points, effectively limiting the wheel and preventing it from rotating. This prevents the vehicle from slipping or swaying significantly under external forces. Additionally, adjusting the spacing between the mounting plates 110 accommodates different wheelbases, and adjusting the distance between the locking units on the same side accommodates different wheelbases, thus expanding the applicability of the entire tilt support 1.

[0042] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
